Prepare a pair of host(host1 and host2), guest is running on the host1, run the following cmd in the host3 , Register host1 , host2 and guest1 to stage candlepin server successfully.

virt-who run in the libvirtd mode.

# ssh -X root@[host1's ip]
# virt-manager
2 In the Terminal2, ssh login to the host2, bring up the virt-manager
# ssh -X root@[host2's ip]
# virt-manager
3 Make sure the virt-who and libvirtd is running in the host1 and host2
# service virt-who status
# service libvirtd status
4 In the Terminal1, Live Migrate guest1 from host1 to host2 
# virsh migrate --live [guestname] qemu+ssh://[host2's ip]/system

5 Check the pop up message in the terminal1(host1):
